Abstract
There is disclosed a portable fire alarm apparatus which comprises a foldable housing consisting of a base assembly having a surface for resting upon a horizontal plane. A central section is pivotally mounted to the base assembly to extend in the vertical plane. Pivotally mounted to the top of the central section is a top planar section which is pivotally mounted and adapted to be positioned in the horizontal plane where it is above and parallel to the base assembly and held in position by means of lockable hinges. The top section contains a smoke or heat detector with the central section containing a speaker or an alarm, with the base section containing electrical circuitry and a power source for alarm operation. The central section has an internal surface which is concave to act as a sounding surface for the audio signal indicative of an alarm condition. The base assembly contains a test indicator which operates in conjunction with a switch to enable a user to turn the unit OFF when not in use and to test for proper battery voltage when the unit is in the unfolded or folded state.
